From the project

Software, firmware, and CAD files for mobile EEG project.

Software, firmware, and CAD files for Brainboard, a mobile EEG project. Brainboard interfaces with a custom MATLAB program, BCI2VR (http://www.engineering.vcu.edu/eegbci/bci2vr_index.html), via Bluetooth. The core hardware components are the ADS1299 EEG front-end from Texas Instruments, the AT32UC3L064 microcontroller from Atmel, the MPU-6050 6-axis inertial measurement unit from InvenSense, and the RN-42 Bluetooth 2.1 module from Microchip/Roving Networks.
